Chapter 16: Problem 42

The lubrication of gears and gear systems is important for successful, efficient operation. Search the Internet and identify and discuss typical methods of providing lubrication for gear systems.

Short Answer

Expert verified
Different methods of lubricating gear systems include oil bath lubrication, splash and spray lubrication, force feed lubrication, and mist or aerosol lubrication. Each method has its own advantages and applications depending on the design and requirements of the gear system.

Step by step solution

01

Method Identification

Investigate online to identify different methods of lubricating gear systems. Typical methods include: oil bath lubrication, splash and spray lubrication, force feed lubrication, and mist or aerosol lubrication.
02

Discussion of Oil Bath Lubrication

Discuss the first method, oil bath lubrication. In this method, the gear is partially submerged in a pool of oil. As it rotates, it carries some oil which spreads across the gear system, providing the required lubrication.
03

Discussion of Splash and Spray Lubrication

Next, discuss splash and spray lubrication. In this method, some gears are partially submerged in oil. As they rotate, they splash oil onto other parts of the gear system. Sometimes, nozzles are used to spray oil onto the gears.
04

Discussion of Force Feed Lubrication

Now, explain force feed lubrication. Here, oil is pumped directly to the gears and bearings under pressure. It is often used in large systems where adequate lubrication cannot be achieved by other methods.
05

Discussion of Mist or Aerosol Lubrication

Finally, discuss mist or aerosol lubrication. This method uses an oil mist generator to produce a mist of oil and air that is directed to the gears. It is often used for systems that cannot retain oil, such as vertical or high-speed gears.

Search for information on wear damage to plastic worms and worm gears and list several articles dealing with this topic.

An automobile with a standard differential is stuck on an icy road, to the extent that the car does not move. The frustrated (and not very intelligent!) driver floors the accelerator and notes that the speedometer reads \(75 \mathrm{mph}\). To what normal car speed does the rotation of the spinning wheel correspond? (This illustrates the kind of "foreseeable abuse" that the engineer needs to take into consideration.)

An industrial machine utilizes a simple planetary train with 24 teeth in the sun and 120 in the ring. The teeth have a 4-mm module in the normal plane, and the helix angle is \(0.42\) rad. The manufacturer wishes to make available optional gearing using the same arm, a 27 -tooth sun and a 111 -tooth ring. If teeth of the same module are used, what is the helix angle?

A 25 -tooth helical gear with \(\psi=20^{\circ}\) has a \(25^{\circ}\) pressure angle in the plane of rotation. What is the pressure angle in the normal plane, \(\phi_{n}\), and the equivalent number of teeth, \(N_{e}\) ? What pressure angle and number of teeth would a straight spur gear tooth of comparable bending strength have?

A 30 -tooth helical gear with \(\psi=25^{\circ}\) has a \(20^{\circ}\) pressure angle in the plane of rotation. What is the pressure angle in the normal plane, \(\phi_{n}\), and the equivalent number of teeth, \(N_{e}\) ? What pressure angle and number of teeth would a straight spur gear tooth of comparable bending strength have?
